Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

15 notecards = 4 pages (4 cards per page)

PHYSICS Q4M1

front 1

1. A strong permanent magnet is plunged into a coil and left in the coil. What is the effect produced on the coil after a short time?

back 1

there is no effect

front 2

2. The Law that states that the direction can induced current is such that its own magnetic field opposes the original change in magnetic flux that induced the current.

back 2

Lenz's law

front 3

3. Lenz’s law concerning the direction of an induced current in a conductor by a magnetic field could be a restatement of?

back 3

Law of Conservation of Energy

front 4

4. To determine the directions of the induced magnetic fields, currents, and emfs the following steps are observed EXCEPT

back 4

make a sketch of the situation for use in visualizing and recording directions

front 5

5. A permanent magnet is dropped, south pole-down, through a conducting loop as shown. As the magnet falls toward—and then falls past—the area of the loop, what will be the direction of the current flow?

back 5

Clockwise when falling toward, but counterclockwise as falling away

front 6

6. A circular loop of wire is placed in a magnetic field as show below. If the magnetic field is increasing, what direction is the induced current in?

back 6

counterclockwise

front 7

7. A loop of conducting wire with length L and width W is entering a magnetic field B at velocity v. What direction will the induced current travel in?

back 7

counterclockwise

front 8

8. What is the direction of the magnetic force on the loop as it enters magnetic field B?

back 8

up

front 9

9. A loop of wire sits in an unchanging magnetic field. Which of the following is a NOT a way to induce a current through the loop?

back 9

Spin the loop about its center

front 10

10. Which of the following statements is NOT true about DC current flow?

back 10

All DC powered items need to be plugged in.

front 11

11. The unidirectional current is called

back 11

direct current

front 12

12.The supply of electrical energy for a consumer is usually by AC because

back 12

the voltage drop in cables is minimal

front 13

13. Why is alternating current transfer more effective than dc current transfer over long distances?

back 13

due to step-up and step-down transformers reducing I2R losses

front 14

14. AC is produced by a generator and its charge is

back 14

negative and positive

front 15

15. The amount of force the electrons are moved in a circuit is called _______.

back 15

emf
